Novel Trends in the Development of Metallic Materials for Medical Implants

Abstract:

Metallic biomaterials are currently used in medicine for fabrication of various kinds of implants like joint and bone replacements, dental implants, stents, fixation devices for fractured bones etc. Their advantages over polymeric or ceramic biomaterials are in higher strength, fracture toughness and fatigue life. In addition, metals can be simply processed by established technologies known for centuries. Due to the increasing average age of human population, there are growing requirements for mechanical and functional performance of implants. Therefore, extensive research and development activities are focused on new directions in this area including new surface treatments and alloys with improved biocompatibility and mechanical performance, porous biomaterials, biodegradable metallic materials. Biodegradable materials are explored as alternatives for fabrication of temporary medical implants like stents and fixation devices (screws, plates, nails) for fractured bones. The present paper focuses on new Mg-and Zn-biodegradable alloys. Advantages of these materials are characterized with respect to mechanical performance and corrosion behavior.
